Everything colour has a use-by date, so don't think it won't go out of fashion! As someone mentioned ^^ think back to the Avocado kitchens etc some years ago. We had friends who built a new house and the 'whole' interior was Avocado although I never shared my thoughts at the time, privately I keep thinking 'what will that look like in 20 yrs time?' I always prefer to keep 'fixtures' to a neutral palette and add colour with accessories as these can easily be changed. Eg, in a bathroom, just changing the colour of the towels will make a huge difference.
While I like the style of kitchen in the photo, I really dislike blue (long story) but if the doors are painted, then if I was a prospective purchaser, I would get a quote to have the doors professionally re-painted, this can be done by any professional auto spray painter. However, if they are vinyl or a laminate this is not possible.
Would you consider an off-white or other neutral and have blue accessories....toaster/towels/etc.
I've been looking at real estate listings and found what I thought was the perfect house...but...the kitchen was a deep, royal purple and bright red with black oven/fridge/etc. Ouch!! It was so dark and horrible, but didn't have painted doors which would have meant a whole rip-out-and-replace and wasn't economically feasible, so it was bypassed immediately.
After many years of working in govt offices I really dislike grey but again it paint can change the colour it might be a possibility.
5 years until your 'possible' sale is not a long time. Just my thoughts and good luck with your decision.
